omarchy-notification-send, merged into quattro, takes an action label and a program, up to three buttons, and exec and action cannot be combined. The words are literals at the call site, ending at the next action, with, or exec argument. A with argument is the data, appended to every action, so untrusted data stays at the end.

The first action is also the card click. The shell shows the buttons on hover in an open deck, with the actions mark beside the title the rest of the time.
